CM93 – This is a link to my public Dropbox which holds the 2011 CM93 chart set in an 82 x 10Mb zip set.

I did it that way because the overall size is large and takes a long time to download, so if a small file fails to download it’s quick to reload it. They are zipped my me, so I know that they are a clean copy, no trojans or viruses​.

They are zipped as a linked set using 7zip, I’m not sure if you need to use 7zip to unpack them or if other modern zippers can handle them, but 7zip is readily available HERE

    Nice website!
    Planning a sailing week with friends in a bareboat charter along the Jurassic coast this may, I was looking for local sailor’s info on the capes and races and found your website.
    We do this area for the first time (we sail our own boats in Belgium and the Netherlands) and our former sailing weeks together were Brittany and the Channel Islands most of the time. Keep up the good work and thanks for the useful info !

    Best regards,

      PB is more wind dependant than lunar.
      Inner passage – upto a 4 if into wind, 5 if a big boat, up that all by one if going with the wind. Stay spitting distance in.
      Outside the race, 5 to 6 miles off then PB has no real effect.
      Thanks for your comment, Monty
